Reversible logic is an emerging technology with wide spread applications in the field of digital systems. The term RAM refers to memory that is accessed with an address and has latency independent of address. In semiconductor memories RAM usually refers to volatile memory read/write memory as opposed to ROM (read only memory). The 2n×2m×1 RAM has n rows and m columns, out of which one bit is selected...
The internet play an vital role in accumulating the Data, even from different location, easily available to all users all over the world. However, the majority of this data are not of much concern to most of the web users as their interest vary over the time. Nowadays there exists more than a billion web sites providing necessary information to users with precise data within fewer page access delay...
Many fields of science, engineering, finance, mathematical optimization methods, Artificial Neural Networks, signal and image processing algorithms requires the operations and manipulations of real numbers. Floating-point operations are most extensively adopted approach for exploiting real numbers. The speed of Floating-point arithmetic unit is very crucial performance parameter which impinges the...
The structure of modified tree multipliers with different adders is presented. Multiplication is an important fundamental arithmetic operation in all microprocessor circuits and algorithms. Currently the speed of multipliers is limited by the speed of adders used for partial products addition. In this paper Conventional Array Multiplier and Dadda Multiplier are compared with the Wallace multiplier...
Built in Logic Block Observer (BILBO) is a bank of flip-flops which are used for self-testing for complex digital IC's in pipeline approach. As per the Launder's principle, KTln2 heat is dissipated if there is any loss in bit. Since BILBO is designed with irreversible logic gates we observe large amount of leakage power which affects its performance. So by keeping this as main criteria, our paper...
Delay has been found as one of the most crucial factors determining the Quality of Experience (QoE) in synchronous video-mediated communication. The effect has been extensively studied for dyadic conversations and recently the study of small group communications has become the focus of the research community. Contrary to dyads, in which the delay is symmetrically perceived, this is not the case for...
Orthogonal Frequency Division Multiplexing (OFDM) has achieved substantial attention in the past couple of the years. In our contemporary world the need for quicker data transmission is not at all-ending. OFDM modulation technique gives us with a way of more thickly packing modulated carriers in the frequency domain than other Frequency Multiplexing methods, thus attaining higher data rates through...
This paper presents the modification of existing prominent multipliers like Wallace multiplier and Truncated Multiplier in order to improvise them in terms of power and area. In the existing Wallace multiplier architecture, the Carry Save Adder is replaced with Modified Carry Save Adder (MCSA)and further the full adder in the MCSA is implemented using Multiplexer. Similarly the regular full adder...
